5 Claims.

The present invention is a continuation in part of my copendingapplicationSerial No. 698,528 led November 17, 1933, for BottleStoppers, filed in the name of 4Jos Luis Conde Perez, Perez being mymaternal surname, which I have dropped in ling this application, and theinvention refers to an automatic closure device, for preventing therefilling of bottles, vessels and the like, as also to the system foranchoring same in the interior of the neck of the bottle.

On designing same, care has been taken that same be as simple aspossible, having into account that means be provided for obtaining aconvenient exit of the liquid when pouring, independently of theentrance of air, for the ypurpose that such exit of liquid vbecontinuous.

The seat of the valve with which is provided the closure device, isdivided by means of a central partition, so that there exist in the saidseat two passages, one for the liquid and the other for the air, bothbeing closed or opened at the Asame time by means Vof the same valve.

As a modified form of construction, the closure device may be providedwith two valves, one of them being a iioating valve for preventing anypossibility of refilling the bottle when this is placed in theup-side-down position.

The closure device is fixed in the interior of` the neck of the bottle,by means of two or more small plates of elastic material, such as corkor rubber, which are adhered to the lateral surface of the closuredevice and at the same time to the internal surface of the bottle neck.These small plates may serve as labels, printing or otherwise applyingon them the trade-mark lof the product or any other sign that Will beseen from the exterior, through the neck of the bottle.

Moreover, for making vthe anchoring of the closure device more effectiveand for l.preventing the insertion of a wire or similar device betweenthe closure device and the internal surface of the neck of the bottle,same is provided with two bands of elastic material, cork or rubber,that encircle the closure device, leaving between same, at each side,respective free spaces thatserve Aas passages for the exit of theliquid.

These two bands are .placed in such-a .form that the vfree spacesmentioned occupy a position perpendicular to the openings of Vtheclosure device that correspond to the exit -of the liquid and to theentrance of the air.

These elements, plates "forming `rthe guarantee labels and bands thatthe closure device carries, are adhered to the internal surface .of the:bottle neck and if an attempt .is made to withdraw (Cl. 21S-22) theclosure device from its place, that said plates and bands will becomespoiled and being then visible from the exterior of the bottle, theviolation would be putin evidence. Y

With the object that the invention be clearly 5 understood and easilycarried into practice, same has been shown on its preferred form ofconstruction in the drawings that accompany this specification.

Fig. l2 shows a` vlengthwise cut View similar to 40 that of Fig.v 3,illustrating a closure device provided with double valve, one of thembeing a floating valve, and

Fig. l3showshow these elements work when it is intended to reiill thebottle, being thus placed 45 in the up-side-down position,

In the drawings, the same Vsigns of reference designate 'similar orequivalent parts.

'Theautomatic closure device, formed of asingle part, lis'constituted`by'two VVprincipal parts; one '50 serving as `a defence 'is provided4with the yducts for theexiit 1of the liquid andthe entrance of the airand the other constituted by the seat offthe valve :and .the.corresponding valve. u

It hasfbeen indicated as l the body Lthatcanies '55 the ducts 2 for theexit of the liquid and 3 for the entrance of the air, adopting theseducts the form shown, i. e. zig-Zag with acute angles, with the objectthat from the exterior of the bottle, it will be impossible, with theaid of a wire or the like, to spoil the valve. The said body forms asingle part with'the seat of the valve 4, being united by means ofpartial walls 5, that provide in the .centre of the closure device, anempty space 6,.

The seat 4 of the valve is divided, transversally, by means of a centralpartition I so that two passages are provided, one 8 placed in thedirection of the duct 2 and another 9, placed in the direction of theduct 3, the bottom vone, of which, for any position of the bottle,serves for the exit of the liquid, while the top one ylserves .for theentrance of the air. Both passages are ,covered with a single valve IIJ,which, in the normal vertical position of the bottle, the said valve ispressed by a counterweight II, that is placed in space 6, the saidcounterweight adopting the form lsimilar to that of a Vcut invertedpyramid, as it is clearly seen in the drawings.

This counterweight I I, is provided laterally with hollows I2 and I3 forfacilitating, respectively, 'the exit of the liquidand the entrance ofthe air.

The working of the said elements may be readily understood by referringIto the illustratin`gidrawings.` As it can be seen in Fig. 8, it issufficient to incline the bottle and under these conditionscounterweight II will fall, as also the Valve -I Il, permitting the freeexit of the liquid that follows the arrows m, flowing through passage 8,hollow I2, duct 2 that are placed in the same direction, flowing afterto the exterior. At the Vsame time, the air enters following the arrowsn,f`flowingA through duct 3, hollow I3 and passage 9, arriving to theinterior of the bottle. -The-valve only lopens when the bottle is turnedand in the horizontal position of same and even before reaching thatposition, the valve I0 closes, as indicated in Figure 10, by the actionof the counterweight II, that rests on the valve. AThis preventstherefilling in this position.

, *For the system ofanchoring, the closure device has'been'provided withtwo lateral hollows I5 where it is vadhered a thin plate I6 of anelastic material such as cork or rubber, that also constitutes aguarantee label, being, for the purpose, printed Vor otherwise markedwith a trade-mark or any other'sign I1 (Fig. 10) that can be seen fromvthe exterior of the bottle or Vessel. This label'or thinplate iscovered by a thin coat I8 of any adhesive xing product that solders samenstrongly to the internal face of the neck I4 of the bottle, so that theclosure device I, by means of these ylabels I6, is made a whole with theneck "I4, of the bottle.

Moreover, towards the top part of the closure device I, 'provision ismade of two thin plates I9'of any elasticV material, that partiallyencircle the Yclosure deviceleaving between theV ends of both, a freepassage 20, .as itcanbe seen in Figures fl, 9,an,d,1'0. I'hese bands I9may be placed, asin thecas'e of label shownin Figure 10, covered withacoat'of a fixing product that will adhere same-*tothe internal surfaceof the neck of the bottle,carryingq also, if necessary, any sign or thename ofthe 4product asindicated'with 2I in Figures 2 and -10 Besidesthat thesetwo ,bands I9 reinforce the farloharing,")of Hthe Yclosure;device, they serve also,

as it has already been said, for diiculting the introduction of a wireor the like between the wall of the closure device I and the internalsurface of the neck, that would make possible to diicult the working ofthe valve. As it will be understood, these bands I9 constitute a defencefor these purposes, since if a wire is introduced through the freespaces 20, the wire will meet label I6.

Ifit is intended to withdraw closure device I, as soon as this has beenslightly moved, is produced a displacement of the label I6 and as sameis adhered to the neck, label I6 will be spoiled, and will present theappearance indicated in Figure 11.

This fact will also be denunciated by sign or mark 2| of bands I9 ifthey have been adhered to the neck of the bottle, as in the former case.

The free spaces 20 provided between the ends of the bands I9, serve as ahelp to the pouring, since they facilitate the exit of the liquid andthe entrance of the air.

In the top part of the neck of the bottle, a free space 22 may beprovided, for permitting the insertion of a usual cork.

In the modified form of construction shown in Figures 12 and 13,addition has been made of a valve or floating element 23, of cork orlthelike.

In the normal vertical position ofV the bottle, this valve, has noinfluence, but on the contrary, it has effect when it is intended torell the bottle in the up-side-down position as shown in Figure 13. If aslow current of-liquid is initiated towards the interior of the bottle,as it is indicated with the arrows p, for little by little makingcompression of the air in the bottle, the floating valve will be raisedcarryingV the valve I0 to apply lagainst theseat 3, for preventing theentrance of the liquid.

Itis evident that many modifications may be introduced in theconstruction and details, without departing from the scope of theinvention which is more clearly set forth in the claims that' follow thepresent specification.

Having now particularly determined and ascertained the nature of myinvention and how same can be carried into practice, I declare that whatI claim, is: Y l
